ypserv Crashes

When the ypserv process crashes almost immediately,
and does not stay up even with repeated activations, the debug process is
virtually identical to that described in ypbind Crashes. Check for the existence of the rpcbind daemon
as follows.

ypserver% ps-e| grep rpcbind

Reboot the server if you do not find the daemon. Otherwise, if the daemon
is running, type the following and look for similar output.

If there are no entries, and ypserv is unable to
register its services with rpcbind, reboot the machine.
If there are entries, de-register the service from rpcbind before
restarting ypserv. To de-register the service from rpcbind, on the server type the following.

# rpcinfo-dnumber 1
# rpcinfo-dnumber 2

where number is the ID number reported by rpcinfo (100004, in the example above).
